The LX-AC photovoltaic AC combiner box is an important component suitable for photovoltaic string power generation systems, connecting string inverters with AC distribution cabinets or step-up transformers. The combiner box features circuit breaker inputs and outputs that use either circuit breakers or load isolation switches. After busbar convergence, it employs a two-level lightning protection system, with a maximum system rated voltage of AC 690V. Its protection level is the same as that of string inverters, rated at IP65, meeting outdoor installation requirements and providing protection against water, dust, UV rays, and salt corrosion.

This product greatly simplifies the wiring between string inverters and AC distribution cabinets or step-up transformers. Its internal structure is clear and organized, with neat and reasonable wiring. It is highly reliable and easy to maintain. Designed for outdoor wall-mounted installation, it can withstand various harsh environments. In addition to standard materials and sizes, it can also be customized according to user requirements.

• The combiner box has a protection rating of IP65, meeting the requirements for outdoor installation in a wall-mounted, sealed cabinet;
• Supports connection to multiple inverter circuits simultaneously, with each input line protected by a thermal-magnetic circuit breaker and a rated voltage of AC690V;
• Equipped with a dedicated high-voltage surge protector to provide overvoltage and lightning protection between the three phases, with an operating voltage of AC480V or higher;
• All busbars inside the box are connected using electroplated or purified busbars to reduce internal resistance and connection points;
• The output uses circuit breakers, load isolation switches, or fuses.
